Landscape Fabric Solutions for Mulch Retention on Slopes

Need landscape fabric to hold mulch on a hillside. What type works best for slope applications?

Fabric Types and Applications

Standard Landscape Fabric (Woven Polypropylene)

• Designed for soil coverage under mulch
• Degrades in direct UV exposure – must be covered
• Not suitable for exposed slope applications

Temporary Erosion Control Netting (Best for Slopes)

• Jute netting – Natural fiber, biodegrades in 1-2 years
• Burlap netting – Similar properties, slightly more durable
• Coconut coir blankets – Longer-lasting (2-3 years), better for steep slopes
• Straw/coconut blends – Good middle ground

Implementation Strategy

1. Prepare slope: remove weeds, smooth surface
2. Install drip irrigation if needed
3. Lay netting: start at top, overlap edges 6-12 inches, staple every 1-2 feet
4. Cut X-shaped planting holes for plants
5. Apply 2-3 inches mulch over netting
6. Plant aggressive groundcovers immediately

Critical Success Factors

• Netting is temporary – Plan for plants to take over slope stabilization within 1-2 years
• Choose vigorous spreaders – Creeping juniper, cotoneaster, vinca, sedum
• Staple adequately – Use 6-8 inch landscape staples, more on steep sections
• Address drainage – Prevent water concentration that undermines netting

Where to Source

• Commercial landscape supply houses (best selection)
• Erosion control specialists
• Online: search "jute netting erosion control" or "coir blankets"
• Some big-box stores carry small rolls

Remember: no fabric permanently holds mulch on slopes. The long-term solution is dense, root-knitting vegetation.
